问题 In one of our community sites, we allow users to upload images. These images are approved or rejected by our moderators. To limit the work needed by our administrators, we want to 'log' each picture that is rejected to some kind of database, and do a lookup in this database prior to submitting an image for approval. If a similar image already has been rejected, the uploaded image won't be submitted for approval. We can of course just log stuff like filename, size and MD5 of the picture for

问题 I would like to use Simulated Annealing to find local minimum of single variable Polynomial function, within some predefined interval. I would also like to try and find Global minimum of Quadratic function. Derivative-free algorithm such as this is not the best way to tackle the problem, so this is only for study purposes. While the algorithm itself is pretty straight-forward, i am not sure how to efficiently select neighbor in single or n-dimensional space. Lets say that i am looking for

问题 We have a field that contains HTML markup for formatting on the website, but we need to query just the text that should render on screen, not things like CSS tags, tag names, property names, etc. Is there a way to ignore the markup right in the SQL query or Stored Procedure? If there are ways to do this, will we have performance issues later on? My guess is that there is some way to use the angle brackets to parse the fields for searchable text. 回答1: Here's a User Defined Function for just

问题 I develop a web application that let users to upload files like images and documents. this file divided into two parts : binary files document files I want to allow users to search documents that uploaded. specialy using full text search. What data types I should use for these two file types? 回答1: You can store the data in binary and use full text search to interpret the binary data and extract the textual information: .doc, .txt, .xls, .ppt, .htm. The extracted text is indexed and becomes

问题 I set up a custom search form to search and display results of my custom post type. The form is: <form class="search-form" action="<?php echo home_url( '/' ); ?>"> <input type="search" name="s" placeholder="Search…"> <input type="hidden" name="post_type" value="resource-library"> <input type="submit" value="Search"> </form> In my search.php I want to direct folks to a custom search php file called search-resource-library.php if the content type is resource-library. So I put this at the top of

问题 Basically as the question states. I am fairly new to Python and like to learn by seeing and doing. I would like to create a script that searches through a text document (say the text copied and pasted from a news article for example) for certain words or phrases. Ideally, the list of words and phrases would be stored in a separate file. When getting the results, it would be great to get the context of the results. So maybe it could print out the 50 characters in the text file before and after

问题 Does anyone have a good reference for a set of Java code implementations of common searching and sorting algorithms. There are many ways to skin a cat (its easy to find Java code of various algos on the net), however is there a list of the most efficient ways in Java to implement these various algorithms? There is for example the http://www.algorithmist.com but most implementations are in C/C++. Cheers! 回答1: I'd suggest looking at the Java Standard Library source code itself. The Collections
